With its delicate but ornate blossoms, the passion flower (Passiflora) is considered by many to be the most beautiful of all vine flowers. Its name is based on the appearance of the flower's pistils, said to resemble the three nails and five wounds of Christ. Flower color for various species is purple, blue, red and white; some are evergreen while others are deciduous. As many selections of Passiflora are vigorous growers, grow on trellis or walls. Attracts wildlife, including butterflies and caterpillars. Some species to consider: Passiflora x alatocaerulea have pinkish-purple flowers on evergreen plants (where it's hardy). P. coccinea produces bright red blooms on evergreen plants (where it's hardy). USDA Zones 9 to 11, depending on species. Perhaps the most cold-hardy passion vine is P. incarnata, which is native to the southeastern U.S. Flowers are pink and purple and appear in mid- to late-summer. USDA Zones (5)6 to 9.
